Y-3=4/7 (x-1) into standard form?

The "Standard form" for a linear equation:

Ax + By = C, where (1) A should not be negative, (2) A and B shouldn't be zero, and (3) A, B, C should be integers.

Similarly, Ax + By + C = 0 is called the "General form".

y - 3 = 4/7 (x - 1)

7 (y - 3) = 4 (x - 1)

7y - 21 = 4x - 4

-4x + 7y = - 4 + 21

4x - 7y = - 17
